>>58711198The charm of Yugi is that he's already pretty much at the top, and you are seeing how he can pull off a victory, even when his opponents are pretty awful people
Yugi's best friend, Joey, is the actual underdog character, as he starts that series pretty shit at dueling, but works his way up into being a respected duelist by the end of the series, he gets the hero's journey, just he's not the protagonist, but he's still one of Yugi's number 1 ride or dies
Joey's development got to a point where he actually almost defeats the main antagonist of the Battle City arc
